Any two of the alkali metals, group I of the Periodic Table:
Li, Na, K, Rb, Cs
and one extra: the only non metal in group I Hydrogen (H2).

What is characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens typically contain seven electrons, making them highly reactive and likely to gain one electron to achieve a stable electron configuration. Additionally, halogens have a tendency to form negatively charged ions when they react with other elements by gaining one electron.
What is the characteristics about the outer electron shells of halogens?
The outer electron shells of halogens have seven electrons, making them one electron short of a full outer shell. This makes halogens highly reactive as they tend to gain an electron to achieve a stable electron configuration. Halogens are located in Group 17 of the periodic table.
What is characteristic about the outer electron shells of alkali metals?
since all the alkali metals have one electron in there outer most shell so there valency is always one & they are the most electropositive elements in the periodic table.they loose one electron from there outermost shell to form one positive charged cations.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
What are the elements in the first group that have one outer shell electron and that are very reactive called?
The elements in the first group with one outer shell electron and high reactivity are called alkali metals. This group includes elements such as lithium, sodium, and potassium. Alkali metals readily lose their outer electron to form positive ions in chemical reactions.
What is characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens typically contain seven electrons, making them highly reactive and likely to gain one electron to achieve a stable electron configuration. Additionally, halogens have a tendency to form negatively charged ions when they react with other elements by gaining one electron.
How many outer shells does beryllium have?
Beryllium has one outer electron shell with two electrons.
What is the characteristics about the outer electron shells of halogens?
The outer electron shells of halogens have seven electrons, making them one electron short of a full outer shell. This makes halogens highly reactive as they tend to gain an electron to achieve a stable electron configuration. Halogens are located in Group 17 of the periodic table.
In the first group of elements in the periodic table what does the first group have in common?
They all have one valence electron in their outer shells and so tend to lose that electron in chemical reactions, gaining a +1 charge.
What is a co-valent compound?
a covalent bond involves the elements sharing electrons to fill outer shells rather than one element donating an electron to the other.
What is characteristic about the outer electron shells of alkali metals?
since all the alkali metals have one electron in there outer most shell so there valency is always one & they are the most electropositive elements in the periodic table.they loose one electron from there outermost shell to form one positive charged cations.
Why are Neon and Argon such nonreactive elements in the periodic table?
Neon (atomic number 10) and Argon (atomic number 18) mostly do not react with other elements because their outermost electron shells have a full complement of electrons. When two elements combine into a molecule they share electrons from their outermost electron shell. This happens when one element has a minimal number of electrons in its outer shell and the other element has an almost full complement of electrons in its outer shell. When they share electrons, they both have the equivalent of full outer electron shells. Since both Neon and Argon have full outermost shells by themselves they do not have a tendency to share electrons.
Are alkali metals active?
because they have outer electrons than can merge with other elements. all elements want to have full outer electron shells, and they only have a few outer electrons.
What is the outer electron configuration for all group 1 elements?
The outer electron configuration for all group 1 elements is ns1, where n represents the energy level of the outermost electron. This means that group 1 elements have one electron in their outermost shell.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
What does elements in groop one have in common?
They all have one electron in the outer most shell
